- the activated form of the acid will normally be a C1-C4 alkyl ester of the formula R1CO2R3, where R3 is C1-C4 alkyl, preferably ethyl.
- R1CO2R3 is C1-C4 alkyl, preferably ethyl.
- acid halides or acid anhydrides can also be used.
- the reaction should be carried out in the presence of a base strong enough to generate the anion of the compound of formula (I).
- bases which may be mentioned are alkali metal hydrides, such as sodium hydride, alkali metal hydroxides, such as sodium methoxide or sodium ethoxide, alkyllithium compounds, such as n -butyl lithium, or alkali metal amides, such as lithium diisopropyl amide.
- the present reaction should be effected at a temperature within the range of from about 0°C to about 100°C, preferably from about 0°C to about room temperature (22°C), in an inert organic solvent such as toluene or diethyl ether.
- a preferred synthesis proceeds through a compound containing an alkyl group in which all or all but one of the hydrogen atoms have been replaced by fluorine atoms, preferably trifluoromethyl, said compound being in the alkali metal salt form. That compound is contacted with a strong base, such as sodium hydride, to form an anion, which is then reacted with the acid fluoride of the desired fluorinated cycloalkyl carboxylic acid.
- a strong base such as sodium hydride
- the anion is generated, wherein R4 represents a C1-C4 fluorinated alkyl group, preferably trifluoromethyl.
- This anion then reacts with an acid fluoride of the formula R1COF, where R1 represents a C3-C6 fluorinated cycloalkyl group, to form a compound of the formula Hydrolysis of this product with an aqueous mineral acid such as hydrochloric acid yields a compound of the formula in which R1 is a C3-C6 fluorinated cycloalkyl group.
- the compounds of the present invention are highly acidic in nature and readily form alkali metal salts. Therefore, the products of the above-described processes are routinely obtained in the salt form. If the free acid form is desired, however, it is only necessary to take the product through an acidic step as the reaction mixture is being worked up. For example, a brief wash with a dilute strong acid, such as dilute hydrochloric acid, readily converts a salt to the free acid.
- a dilute strong acid such as dilute hydrochloric acid
- Sodium ethoxide was prepared by reacting 3.6 g of 50% sodium hydride (75.0 mmol of sodium hydride) and 3.5 g (76.0 mmol) of ethanol in 100 ml of diethyl ether. The solution was cooled to about 5° and 9.0 g (37.0 mmol) of ethyl 2,2,3,3,4,4,4-heptafluorobutyrate were added. Then 7.0 g (37.0 mmol) of 3,5-dichloroacetophenone were added and the mixture stirred for two hours. The mixture was poured onto ice along with 50 ml of a 10% disodium hydrogen phosphate solution.
- Representative compounds were tested in cattle using a single intraruminal injection of the desired dose of the compound dissolved in 10 ml of polyethylene glycol.
- the cattle were calves weighing at least 165 kg, housed in environmentally controlled pens. Two calves were used for each compound tested.
- the calves were fed on a conventional mixed feed which provided adequate nutrients and energy. Feed and water were available to the calves at all times.
- dental wicks were saturated with the above blood serum and then placed in Petri dishes containing adult stable flies and in test tubes containing blow fly larvae. After 24 hours, the insects were examined and the number of dead counted.
- a compound was considered to be active, for purposes of the present disclosure, on any day in which at least 50% of the insects were killed upon exposure to the saturated wick.
- Certain compounds were further tested by exposing dental wicks saturated with blood serum, per the method described above, to insects for 48 hours rather than 24 hours. After 48 hours, the insects were examined and the number of dead counted. Again, a compound was considered to be active, for purposes of the present disclosure, on any day in which at least 50% of the insects were killed upon exposure to the saturated wick.
- Representative compounds of the invention were also tested in cattle using multiple intraruminal injections of the desired dose of the compound.
- the multiple injections consisted of daily administration of a single intraruminal injection for a period ranging from 10 to 18 days.
- the cattle tested were similar in size to those described for the single dose test detailed above.
- Two calves were used for each compound and dose tested. The calves were also fed and watered as previously described.
- the daily dose of compound to be tested was prepared using one of two methods. In one method the desired dose was prepared, daily, prior to administration, by dissolving the required daily amount of test compound in 5 ml of polyethylene glycol. In an alternative method the entire amount of compound required for the test was dissolved in a sufficient amount of polyethylene glycol such that the resulting solution contained approximately 5 ml of polyethylene glycol for each day of testing. The total volume of material thus prepared was then placed in a capped serum bottle which was suitable for metering out the desired daily dose.
- certain representative compounds of the present invention were also tested using an in vivo test system comprising placing a chamber containing six starved adult stable flies on the back of the test animal on each test day. The flies were collected daily and the number of dead flies counted. A compound was considered to be active, for purposes of the present discussion, on any day in which at least 50% of the flies had died prior to collection.
- the calves were given daily intraruminal injections for periods ranging from 10 to 18 days and then the injections were stopped. Both in vitro and in vivo testing was continued for several days beyond the administration period, preferably until no further insecticidal activity was observed. Thus, the tests evaluated the systemic activity of the compounds, and also the length of time during which the compound persisted in the animal's system.
- Tables II and III report test results of representative compounds. The compounds are identified by their Example numbers above. Table II reports insecticidal activity in the 24 and 48 hour in vitro test system. Table III reports insecticidal activity against adult stable flies in the in vivo test system. Insecticidal results, in both tables, are reported in terms of "days of insecticidal activity". The term "days of insecticidal activity" in Table II is used in the same manner as in Table I above. The same term, in Table III, refers to the specific test days in which at least 50% of the adult stable flies had died prior to collection. Table II Insecticidal Activity Following 24 and 48 Hour In Vitro Exposure of Insects to Cattle Sera Compound of Ex.
- the activity of the compounds of the invention against Lone Star ticks, Amblyomma americanum was determined as follows. Two calves were given a daily 1 mg/kg intraruminal injection of a solution consisting of the required amount of the compound of Example 2 dissolved in 5 ml of polyethylene glycol. Two other calves were given a daily 1 mg/kg intraruminal injection of a solution consisting of the required amount of the compound of Example 3 dissolved in 5 ml of polyethylene glycol. Finally, two other calves were used as control calves, with one calf given 5 ml of polyethylene glycol each day while the other calf was left untreated. All treatments continued for a total of 18 days.
- the method of the present invention is carried out by administering a compound of the invention to a host animal to control insect and acarina parasites. Administration to the animal may be by the oral or percutaneous routes.
- Parasitic insects and acarina include species that are bloodsucking as well as flesh eating and are parasitic during all of their life cycle or only part of their life cycle, such as only the larval or only the adult stage.
- Representative species include the following:
- the claimed compounds display systemic ectoparasiticidal activity.
- the compounds have the ability to permeate the tissues of a host animal to which one of the compounds has been administered. Insect parasites which then consume blood or other living tissues of the host animal are thereby killed.
- control entails the destruction of an insect population by killing the undesired insects after thay have consumed blood or other living tissue from the host animal.
- the compounds can be administered by oral or percutaneous routes, and are preferably formulated prior to administration.
- Percutaneous administration is conveniently accomplished by intraperitoneal, intraruminal and intravenous injection of an injectable formulation.
- Oral administration is a particularly preferred route of administration.
- the rate, timing, and manner of effective administration will vary widely with the identity of the parasite, the degree of parasiticidal attack, and other factors. Administration can be made periodically over the entire lifespan of the host, or for only a peak season of parasitic attack. In general, effective parasite control is achieved at administration rates of from about 5 to about 100 mg/kg.
- Oral administration may be performed by mixing the compound in the animals' feed or drinking water, or by administering dosage forms such as tablets, capsules, boluses, or implants.
- ectoparasitic attack generally takes place during a substantial portion of the host animal's lifespan, it is preferred to orally administer the compounds of the present invention in a dosage form capable of providing sustained release over a period of time.
- Conventional procedures include the use of a matrix which physically inhibits dissolution, where the matrix is a waxy semisolid, such as a vegetable wax, a high molecular weight polyethylene glycol, or a copolymeric matrix such as that described in Nevin, U.S. Patent 4,273,920.
- a good way to administer the compounds is by means of a sustained-action bolus, such as those of Laby, U.S. Patent 4,251,506, Davis et al ., U.S. Patent 4,649,042 and Simpson, British Patent 2,059,767.
- Sustained release of the compounds of the present invention can also be achieved by the use of an implant such as from a silicone-containing rubber.
- the compounds are formulated into ectoparasiticidal compositions which comprise a compound of the present invention and a physiologically-acceptable carrier.
- ectoparasiticidal compositions which comprise a compound of the present invention and a physiologically-acceptable carrier.
- Such formulations are well known to those skilled in the art, for example by dissolving or dispersing the compound in one of many physiologically acceptable adjuvants or diluents.
- the compounds can be formulated for oral administration in the usual forms, such as drenches, tablets, or capsules. Such compositions, of course, require orally-acceptable inert carriers.
- the compounds can also be formulated as an injectable solution or suspension, for intraperitoneal, intraruminal or intravenous injection.
- the compounds are conveniently formulated as one component of a standard animal feed.
- the premix can contain from about 2 to 250 grams of compound per pound.
- the premix is then, in turn, formulated into the ultimate feed by conventional mixing.
